Description

Technical Field

[0001] This utility model relates to the field of steel formwork sealing technology, specifically to a segmented splicing leak-proof sealing structure for ultra-high concrete column steel formwork. Background Technology

[0002] Currently, steel formwork technology is widely used in public construction sectors such as railways, highways, water conservancy and hydropower, and rail transit. However, its application in the residential construction sector is relatively limited. Steel formwork offers many advantages over traditional wooden formwork. Made of high-strength steel, steel formwork can withstand the enormous lateral pressure and impact during concrete pouring, ensuring the formwork does not deform or crack. Its load-bearing capacity is far higher than ordinary wooden formwork, allowing for a greater number of reuses and significantly reducing the cost per use. The surface is treated with rust prevention, providing strong corrosion resistance and allowing for repeated use for many years without damage. Steel formwork employs a modular design, enabling rapid assembly and disassembly using bolts, clips, and other methods to adapt to the needs of components of different shapes and sizes. This rapid assembly and disassembly capability significantly shortens the construction period.

[0003] However, the existing segmented splicing steel formwork has obvious defects in its sealing structure: most seals rely on a single rubber strip to directly adhere to the joint. When pouring ultra-high columns, the lateral pressure of the concrete is extremely high, which can easily cause the rubber strip to shift, be over-compressed and fail, and gaps are easily generated at the joint. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a segmented splicing leak-proof sealing structure for steel formwork of ultra-high concrete columns. This solves the problem that most seals rely on a single rubber strip directly fitting the joint. During the pouring of ultra-high columns, the lateral pressure of the concrete is extremely high, which can easily cause the rubber strip to shift, be over-compressed and fail, and cause gaps to easily form at the joint.

[0005] This utility model provides the following technical solution: a segmented splicing leak-proof and sealing structure for steel formwork of ultra-high concrete columns, including an upper plate and a lower plate. A ring of mounting plates is fixedly connected to the surface of both the upper plate and the lower plate. Each mounting plate has a threaded hole on its surface. The corresponding two mounting plates are connected by bolts. A sealing component is provided at the connection between the upper plate and the lower plate.

[0006] The sealing assembly includes a steel belt and a mounting bracket. A rubber sealing ring is fixedly adhered to the surface of the steel belt. Multiple mounting holes are provided at both ends of the steel belt. The mounting bracket is detachably fixed to the lower plate by bolts. A screw is rotatably installed inside the mounting bracket. A threaded sleeve is threaded onto the surface of the screw. A fixing bracket is fixedly connected to the upper surface of the threaded sleeve. A locking component is provided on the fixing bracket.

[0007] Preferred technical solution 1: A sliding rod is fixedly connected inside the mounting bracket, and a sliding sleeve is slidably sleeved on the surface of the sliding rod, and the sliding sleeve is fixedly connected to the mounting bracket.

[0008] Preferred technical solution 2: The locking component includes threaded grooves formed on both sides of the fixing frame, and a lead screw is threadedly installed inside each of the two threaded grooves. A clamping plate is rotatably installed at one end of each of the two lead screws. Multiple locking rods are fixedly connected to the surface of one of the clamping plates, and the locking rods match the mounting holes.

[0009] Preferred technical solution 3: Limiting grooves are provided on both sides of the fixing frame, and limiting rods are slidably installed inside the two limiting grooves. The two limiting rods are fixedly connected to the two clamping plates respectively.

[0010] Preferred technical solution four: Two limiting rollers are rotatably mounted on the upper surface of the mounting frame.

[0011] Preferred technical solution five: A positioning ring is fixedly connected to the lower surface of both the upper plate and the lower plate, and a positioning groove matching the positioning ring is opened on the upper surface of both the lower plate and the upper plate. A sealing sleeve is fitted on the surface of the positioning ring, and the sealing sleeve and the positioning groove are interference fit.

[0012] Compared with the prior art, this utility model provides a segmented splicing leak-proof sealing structure for ultra-high concrete column steel formwork, which has the following beneficial effects: This segmented splicing leak-proof sealing structure for ultra-high concrete column steel formwork, through the interference fit sealing sleeve of the positioning ring and the positioning groove, not only completes the initial accurate positioning of the upper plate and the lower plate, but also forms the first seal, avoiding grout leakage caused by splicing misalignment; the bolt connection of the mounting plate further strengthens the stability of the formwork body and provides support for subsequent sealing.

[0013] Meanwhile, in the sealing assembly, the rubber sealing ring of the steel belt forms a second leak-proof barrier, and the limiting roller assists the steel belt in smoothly wrapping around the joint; the screw and sleeve, together with the sliding rod and sleeve, ensure that the fixing frame moves smoothly to the designated position, while the lead screw, clamp, clamp, and limiting rod firmly lock the steel belt, ensuring that the sealing ring fits tightly against the joint. The overall leak-proof design is reliable, installation and disassembly are convenient, and it can be reused, reducing construction costs. Attached Figure Description

[0019] Please see Figure 1-4 ,

[0020] Example 1: A segmented splicing leak-proof and sealing structure for steel formwork of ultra-high concrete columns, including an upper plate 1 and a lower plate 2. A ring of mounting plates 3 is fixedly connected to the surface of both the upper plate 1 and the lower plate 2. Each mounting plate 3 has a threaded hole on its surface. The corresponding two mounting plates 3 are connected by bolts. A sealing component is provided at the connection between the upper plate 1 and the lower plate 2.

[0021] The sealing assembly includes a steel belt 4 and a mounting bracket 5. A rubber sealing ring 6 is fixedly adhered to the surface of the steel belt 4. Multiple mounting holes 7 are provided at both ends of the steel belt 4. The mounting bracket 5 is detachably fixed to the lower plate 2 by bolts. A screw 8 is rotatably installed inside the mounting bracket 5. A threaded sleeve 9 is threaded onto the surface of the screw 8. A fixing bracket 10 is fixedly connected to the upper surface of the threaded sleeve 9. A locking component is provided on the fixing bracket 10.

[0022] Example 2: The difference between this example and Example 1 is that the mounting bracket 5 is internally fixedly connected to a sliding rod 11, and a sliding sleeve 12 is slidably sleeved on the surface of the sliding rod 11. The sliding sleeve 12 is fixedly connected to the mounting bracket 10.

[0023] Example 3: The difference between this example and Example 1 is that the locking component includes threaded grooves on both sides of the fixing frame 10. A lead screw 13 is threadedly installed inside each of the two threaded grooves. A clamping plate 14 is rotatably installed at one end of each of the two lead screws 13. Multiple locking rods 15 are fixedly connected to the surface of one of the clamping plates 14. The locking rods 15 match the mounting holes 7.

[0024] Example 4: The difference between this example and Example 1 is that the fixing frame 10 has limit grooves on both sides, and limit rods 16 are slidably installed inside the two limit grooves. The two limit rods 16 are fixedly connected to the two clamping plates 14 respectively.

[0025] Example 5: The difference between this example and Example 1 is that two limiting rollers 17 are rotatably mounted on the upper surface of the mounting frame 5.

[0026] Example 6: The difference between this example and Example 1 is that a positioning ring 18 is fixedly connected to the lower surface of both the upper plate 1 and the lower plate 2, and a positioning groove 19 matching the positioning ring 18 is opened on the upper surface of both the lower plate 2 and the upper plate 1. A sealing sleeve is fitted on the surface of the positioning ring 18, and the sealing sleeve and the positioning groove 19 are interference fit.

[0027] In summary, the segmented splicing leak-proof sealing structure of the steel formwork for the ultra-high concrete column meets the self-locking conditions between the screw 8 and the screw sleeve 9, and between the threaded rod 13 and the threaded groove, and its thread helix angle is less than the equivalent friction angle.

[0028] In use, first align the positioning ring 18 of the upper plate 1 with the positioning groove 19 of the lower plate 2 and engage it. The sealing sleeve and the positioning groove 19 form an interference fit to achieve the initial positioning and first sealing of the template splicing. Then, using the mounting plates 3 on the surfaces of the upper plate 1 and the lower plate 2, fasten the corresponding two mounting plates 3 with bolts through the threaded holes to complete the splicing and fixing of the template body.

[0029] Next, the sealing assembly is installed. First, the mounting bracket 5 is fixed to the lower plate 2 with bolts. Then, the iron belt 4 is wrapped around the connection between the upper plate 1 and the lower plate 2, with both ends of the iron belt 4 resting on the fixing bracket 10. During this process, the limiting roller 17 plays a limiting and guiding role for the iron belt 4. Then, the screw rods 13 on both sides of the fixing bracket 10 are rotated. The screw rods 13 push the clamping plates 14 closer to the iron belt 4 until the locking rods 15 on the surface of one of the clamping plates 14 are engaged in the mounting holes 7 opened at both ends of the iron belt 4, thereby locking the iron belt 4. Then, the handle of the screw rod 8 located outside the mounting bracket 5 is rotated. The screw sleeve 9 on the surface of the screw rod 8 drives the fixing bracket 10 fixedly connected above it to move, thereby tightening the iron belt 4 and making the rubber sealing ring 6 tightly fit the connection between the upper plate 1 and the lower plate 2, forming a second seal. Finally, the leak-proof sealing operation of the entire segmented splicing of the ultra-high concrete column steel formwork is completed, effectively avoiding the problem of grout leakage during concrete pouring.
